One could also have a bus- or socket-activated service to update the motd on demand. The PAM module could then query it. This means - the update process could run as an unprivileged user - no updates if not needed (unlike a cron-based service) - the service could implement a minimum time between updates - no races between two processes updating the motd unless the update service is implemented in a very suboptimal way - as the update service can just exit and will be restarted automatically, there are no useless processes around either If the service is not installed (a good default?), just use a static motd.
